tude 11°6 south, longitude 1634 west, the same day on 
which the maximum sea-surface and air temperatures 
_ were recorded. 
As shown in table 56, the Alaskan Peninsula Group 
presents the highest mean maximum relative humidity 
(98.4 per cent), whereas the lowest mean maximum 
(73.6 per cent) is recorded during the Carnegie’s first 
stay in the Hawaiian Group (Group XVIla). These two 
Groups also present the highest and lowest mean mini- 
mum relative humidities (91.0 per cent and 64.2 per cent 
respectively). 
As indicated in table 54, the relative humidity in all 
Groups is high when compared with similar values for 
continental areas. The mean relative humidity for all 
days is 80.17 per cent, and the mean daily range is only 
11.59 per cent.
